Statsd crashes because predictAnomalyTimestamp requests past buckets
that occurred before time began. That's fine, but statsd needs to know
that the data before time began was 0 (instead of reading before the
beginning of the array and crashing).
AnomalyTracker's use of bucketNumbers is in general risky, and should be
auditted. But this cl will fix the current crashing.
Bug: 73825954
Test: Definitely necessary. Will write during audit.

use same cpu stats readers with BatteryStats so that
1) both throttle to avoid too frequent pulls
2) cached value is served within throttle interval to avoid double
pulling by both statsd and BatteryStats

This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.
Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.
Test: make relevant packages

orientation changes.

+ Metrics will do flushIfNeeded() to correctly move the clock and informing
AnomalyTracker the past bucket info, and then clear past buckets.
+ We will still keep the current bucket data for the validity of the future metrics.

StateTracker is a special condition tracker that's based on a state atom.
State atoms are annotated in atoms.proto.
The rules for StateTracker:
1. must not have "stop". must have "dimension"
2. must be based on a state atom.
3. it must have the all primary fields and the exclusive state field in its dimension.
For example UidProcessStateTracker, will have output dimension {uid, state}.
Test: unit tests added.

This could happen when statsd is disconnected from logd reader. When we reconnect, we are going to
get all events from the buffer again.

+ This is useful when we want to build Anomaly detection on wakelocks, but want to whitelist
wakelocks held by some apps that are whitelisted. It reduces the number of matchers needed
in such a config.
+ Also added the ability to match an AID by string name.
